These two currents are 180° out of phase with each other as shown by the vectors and the sine waves. The resultant line current (15 A) will be equal to the difference between the two currents. Ten amperes will circulate between the capacitor and the inductor. View chapterExplore book ...
Definition of power rating of a resistor is; the maximum amount of energy that a resistor can dissipate safely. Generally, the power rating is one of the specifications of a resistor, and sometimes, it is also called the resistor wattage rating. Joule’s first law states that the electrical ...
The output voltage is always smoothed by a capacitor. Only the non-isolated DC-DC converters are studied in this paragraph. The switches are assumed ideal, as well as passive elements (L, C) 3.1. Buck converter 3.1.1. Operating phases The buck converter circuit is illustrated in figure 5a...
This reactive power can now be supplied from the capacitor installed in parallel with the load in local. The reactive power of acapacitorcan be calculated using the following formula: IMPORTANT: Inpower factor improvement, the reactive power requirement by the load does not change. It is just su...

the maximum continuous discharging rate is typically 1C, which is acceptable for grid application. For high-power applications, a hybrid system can be used where a metal/air battery is connected in parallel to a high-power battery or a capacitor/supercapacitor that supplies power to the connected...
For a step load current change, a marginally stable power supply will have a ringing voltage output, this could be damage voltage sensitive loads, such as logic circuitry in a computer. Step load current response testing checks critical test points, such as defective output filter, capacitor ...
Find power factor from the formula power factor = P / S. Find the angle cos⁻¹(power factor) and draw a power triangle. Calculate reactive power Q from Pythagorean theorem: Q = √(S² - P²). Correct the power factor by adding a capacitor or inductor, the size of which will...
At the end of a charge/discharge cycle, the gate/capacitor combination has moved C·ΔV of charge from Vdd to ground, which uses an amount of energy equal to C·ΔV· Vdd that is independent of the cycle time. The average dynamic power of this node, the average rate of its energy ...
Line regulationis the ability of a power supply to maintain the output voltage given changes in the input line voltage. Load regulationis the ability of a power supply output to remain constant given changes in the load. You shouldexercise caution when sourcing power to capacitive, inductive, an...
